When mining and construction companies across India need rugged, reliable, and high-volume air handling solutions for their demanding operations, they turn to Shivam Engineering & Fabrication. As a leading axial flow fan manufacturer for the construction and mining industry, we have supplied hundreds of units to coal mines, iron ore mines, limestone quarries, tunnel projects, and construction sites across the country. Our axial flow fans are engineered for continuous operation in harsh, dusty, abrasive, and often hazardous environments – perfectly suited for the demanding conditions of mining and construction.

Why Construction & Mining Sites Need Heavy-Duty Axial Flow Fans

Mining and construction operations involve handling abrasive dust (coal, iron ore, silica), confined spaces (tunnels, underground mines), and continuous heavy-duty operation. Standard fans fail quickly in such environments. Our specially designed axial flow fans feature:

• Abrasion-Resistant Construction – Heavy-duty MS with wear liners, Hardox/AR plate, or SS304 for high-wear areas.
• High-Volume Airflow – Capable of handling up to 500,000+ m³/hr for large tunnel and mine ventilation.
• Spark-Resistant Options – Cast aluminum impellers for coal mining and explosive dust environments.
• Flame Arrestors & DGMS Compliance – For underground coal mine ventilation.
• Portable/Mobile Configurations – Skid-mounted or wheel-mounted for easy site relocation.
• Continuous Duty Rating – Designed for 24/7 operation in harsh conditions.
• Reversible Flow Options – For tunnel ventilation systems requiring both supply and exhaust.

Key Applications of Axial Flow Fans in Construction & Mining

1. Tunnel Ventilation

Axial flow fans provide fresh air supply and exhaust in road/rail tunnels during construction (TBM – Tunnel Boring Machine) and for operational tunnels. Reversible axial fans allow both supply and exhaust functions.

2. Underground Mine Ventilation

Main ventilation fans for entire mines and auxiliary fans for development faces in coal, metal, and limestone mines. Features include spark-resistant construction, flame arrestors, and DGMS compliance.

3. Dust Extraction (Crushers & Screens)

High-volume axial fans for dust collection systems at crushers, screens, and conveyor transfer points in mines and construction aggregate plants.

4. Construction Site Ventilation

Fresh air supply for confined space entry, underground construction (metro tunnels, hydropower tunnels), and temporary ventilation at construction sites.

5. Portable Site Ventilation

Skid-mounted or wheel-mounted axial fans for temporary ventilation needs, ideal for short-term mining projects and construction sites requiring mobility.

Axial Fan Types for Mining & Construction

Material & Design Options for Abrasive Mining Conditions

Depending on the material being handled and site conditions, Shivam Engineering & Fabrication offers different construction materials:

• Heavy-Duty Mild Steel (MS) with Abrasion-Resistant Coating – For general construction site air handling and dust extraction.
• Hardox / AR (Abrasion Resistant) Plate – For highly abrasive applications like iron ore dust, coal dust, and mineral conveying. Hardox 400/450 recommended for extreme wear.
• Stainless Steel SS304 – For moderate corrosion and high-temperature applications.
• Cast Aluminum – For spark-resistant applications in coal mines and explosive dust environments.
• Heavy-Duty Fabricated Steel Impeller – For large-volume, high-pressure applications.

DGMS Compliance for Underground Coal Mines

Shivam Engineering & Fabrication understands the critical safety requirements for underground coal mine ventilation. Our axial flow fans for coal mines are designed and manufactured as per DGMS (Directorate General of Mines Safety) standards, including:

• Flameproof construction with flame arrestors
• Spark-resistant aluminum impellers
• Methane gas monitoring ports
• Explosion-proof motors (Exd)
